In this math video tutorial, the elimination method is used to solve systems of equations. The video walks through an example where finding the least common multiple is necessary in order to eliminate one of the variables. The tutorial emphasizes the importance of multiplying all terms by the same factor when using this method. The steps taken to solve the system of equations are clearly explained and easy to follow.
